Proposal for Measured Boot Implementation

by Alexei Fedorov

Hello, I'm preparing the next set of patches for Measured Boot support in TF-A, please find some details on design and implementation below. 1. SHA256/384/512 hash algorithm for Measured Boot related hash calculations is passed as an existing build 'HASH_ALG' build parameter. 2. BL1 calculates BL2 image hash and passes these data to BL2 via FW_CONFIG/TB_FW_CONFIG device tree in new 'bl2_hash_data' byte array added in 'fvp_fw_config.dts'. These changes are part of the patch under review, please see https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3555 3. Event Log is calculated by BL2 in Secure Memory and copied to Non-secure memory. Address in Non-secure memory is calculated as: "nt_fw_config_addr + nt_fw_config_max_size" with values obtained from 'tb_fw_config': nt_fw_config_addr = <0x0 0x80000000>; nt_fw_config_max_size = <0x200>; 4. Event Log address and size is passed by TOS_FW_CONFIG and NT_FW_CONFIG device tree in 2 new added properties: Property name: 'tpm_event_log_addr' Value type is an unsigned 64-bit integer specifying the physical address of the Event Log. Property name: 'tpm_event_log_size' Value type is an unsigned 32-bit integer specifying the size of the Event Log. /* TPM Event Log Config */ tpm_event_log { compatible = "arm,nt_fw"; tpm_event_log_addr = <0x0 0x0>; tpm_event_log_size = <0x0>; }; 5. TF-A provides Event Log to the BL33 (TFTF/UEFI/U-boot) in 'nt_fw_config' device tree, which address is passed by BL31 as 'arg0' parameter, see TFTF patch: https://review.trustedfirmware.org/c/TF-A/tf-a-tests/+/3327 6. A new test which validates and prints Event Log data passed in 'nt_fw_config' to BL33 will be added to TFTF. Please review and provide your comments on the proposed design. Regards. Alexei.

Platforms to maintain their own Change Log files following 2.3 Release

by Lauren Wehrmeister

Hi All, Following the TF-A release planned for April, platforms will be expected to maintain their own Change Log files to document relevant changes in platform specific code. The common TF-A Change Log will no longer document Platform specific updates after the 2.3 release. As a general reminder, it is up to the developer to document changes in common TF-A code that is relevant in the "Upcoming Change Log" file. Reviewers please continue to help determine if documentation is required for a given patch. During each code freeze for a release the documentation in the upcoming change log will be moved to the change log corresponding to the release. Thanks, Lauren Wehrmeister

Re: [TF-A] [RFC] New feature in TF-A to load encrypted FIP payloads: address implementation concerns

For now, I've added in our internal CI a simple build test based on the build instructions you've provided in the patch set. This will at least make sure we do not break the build inadvertently in the future. But as you say, going forward, we should plan for proper testing on QEMU. I am hoping we will soon be able to extend the OpenCI [1] and add this support there.

Actually this is something you have access to, it's a matter of adding a line in docs/change-log-upcoming.rst in the TF-A source tree. Regards, Sandrine

Re: [TF-A] [RFC] New feature in TF-A to load encrypted FIP payloads: address implementation concerns

by Sumit Garg

Hi Everyone, I have tried to address most of the implementation concerns with updated patch-set [1] as follows: *Concern*: Firmware encryption bit needs to be signed *Address*: Moved the firmware encryption bit from FIP ToC header to "io_uuid_spec_t" struct which is part of "plat_io_policy" that is embedded in the boot-loader (BL1 or BL2) and hence firmware encryption bit is signed. Also, with this implementation fip_tool is no longer aware of encryption and just encrypted binaries are piped to fip_tool. *Concern*: Capability to encrypt with different keys for different images *Address*: Passed "img_id" buffer reference as an argument of "plat_get_enc_key_info()" API. So that platforms may choose to either provide a unique key per firmware image or just derive a key from HUK per firmware using "img_id" buffer as a salt. *Concern*: Coupling of FIP and encryption layer *Address*: Firstly I think we all can agree that encryption layer provides confidentiality protection specific to IO storage. Secondly FIP is actually a packaging layer that sits over actual IO layer and having the encryption layer coupled with FIP provides an abstraction layer for any FIP payload which in turn provides the following features: 1. Allows the firmware certificates to be encrypted as well to protect against cloning satisfying R050_TBBR_PROTECTION requirement. 2. Allows the firmware configuration data to be encrypted as well. 3. Provides a capability to have a secure key store as FIP payload which is protected using HUK. *Concern*: Allow usage of alternative verify-then-decrypt method *Address*: A platform could disable this encryption layer and implement decryption as part of "bl2_plat_handle_post_image_load()". Please let me know in case I missed any implementation concerns and feel free to provide your feedback on updated patch-set [1].

Re: [TF-A] Incorrect section attributes with ALLOW_RO_XLAT_TABLES=1

by Petre-Ionut Tudor

Hi Masahiro, That warning is expected. GCC complains about this, since tf_base_xlat_table is not constant and we are asking it to be put in a read-only section (see the REGISTER_XLAT_CONTEXT_RO_BASE_TABLE macro). This is fine since: * We only want the base table to be read-only after the tables have been initialized. The only time we change tf_base_xlat_table is when we initialize it, and at that point in the platform setup sequence the MMU is off, so permissions have no effect. * We never write to this with the MMU on (it's the level 1 translation table), so there is no danger of generating MMU faults. I hope this answers your question. Thanks Petre ________________________________ From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org> on behalf of Masahiro Yamada via TF-A <tf-a(a)lists.trustedfirmware.org> Sent: 06 March 2020 12:30 To: tf-a(a)lists.trustedfirmware.org <tf-a(a)lists.trustedfirmware.org> Subject: [TF-A] Incorrect section attributes with ALLOW_RO_XLAT_TABLES=1 Hi.
